How to add new kernel of one specific sparse storage format

For instance, if I want to add sp2m to the library, the steps are as follows:

1. Add CSR、 CSC、 COO and BSR to headers of "def_x.h" in "include/alphasparse/kernel"

Use the #define to specify the datatype of the same format:

e.g. #define sp2m_csr sp2m_s_csr //for float datatype and csr format

2. Add the declaration of kernels to headers of kernel_format_datatype.h in path "include/alphasparse/kernel

e.g. alphasparseStatus_t sp2m_s_csr(const spmat_csr_s_t *A, const spmat_csr_s_t *B, spmat_csr_s_t **C);

3. Add the user interfaces implementation in "alphasparse_sp2m.cpp" in path "platform/kernel/levelx"

4. Add the kernel implementation, such as sp2m_s_csr.cpp , in path "platform/kernel/levelx".
